Question 12, 9.1.24-T HW Score: 77.14%, 10.8 of 14 points Save Homework: 9.1 - Correlation Part 5 of 5 Points: 0.43 of 1 The accompanying table shows the height (in inches) of 8 high school girls and their scores on an IQ test. Complete parts (a) through (d) below. Click here to view the data table, Click here to view the table of critical values for the Pearson correlation coefficient. (a) Display the data in a scatter plot. Choose the correct graph below. B. D. 68- 120- 120- 68 110 64 64 O 60 100 100- TO score 60- 10 SC 56- 904 90- BO BO 120 52 120 68 Height (inches) Height (inches) Haight (inches (b) Calculate the sample correlation coefficient r. = 0.067 (Round to three decimal places as needed.) (c) Describe the type of correlation, if any, and interpret the correlation in the context of the data. There is no linear correlation Interpret the correlation. Choose the correct answer below. A. Based on the correlation, there does not appear to be any relationship between high school girls' heights and their IQ scores. B. As high school girls' heights increase, their IQ scores tend to increase VC. Based on the correlation, there does not appear to be a linear relationship between high school girls' heights and their IQ scores. As high school girls' heights increase, their IQ scores tend to decrease. E Increases in high school girls' heights cause their IQ scores to increase. Increases in high school girls' heights cause their IQ scores to decrease. (d) Use the table of critical values for the Pearson correlation coefficient make a conclusion about the correlation coefficient. Let a = 0.01. The critical value is Therefore, there |sufficient evidence at the 1% level of significance to conclude that between high school girls' heights and their IQ scores.
